This invention relates to closures for rigid l and semi-ri id collapsible` containers/ for controlling t 1e discharge of the lcontents of the containers.

An object' of the invention is the provision of a closure for containers of the indicated character which may be conveniently and easily actuated, lwhich will be permanently associated with the container, and in which the closure member will be releasably retained in a closed position in a novel manner. c

A further object of the invention -is the provision in a closure construction of-the indicated character havin a closure member which may be moved 1n opposite directions for controlling an outlet in conjunction with means for releasably retaining the closure in a closed position, and which closure member may be moved in either direction to an open position from the influence of the retaining means.

The nature of the invention and its distinguishing features and advantages will appear when the following specification yis read inconnection with the accompanyingl drawing, in which--I Figure 1 is a plan view of one type of container with the closure of the present-invention a plied thereto', the closure member being sliown in an open position.

Fig. 2 is a sectional view takenon the line 2-2 of Fig. 1, a portion of the container body being broken away, and the closure member being shown releasably retained in a closed position.

Fi 3 is a. side view showing the closure mem er in a closed position.

The practice of the present invention will essentially include the use of a .container which may be of any of the t i s used either rigid or semi-rigid collapslb e types, lwhich contain divers commodities suc as powder, pastes, creams and liquid lotions.

Referring now more particularly to the drawing, it will be apparent that, there is shown a container 10 havin a discharge end consistin of a breast 11 aving a neck 12. Thesnec has a discharge passage or outlet 13 which communicates with the interior of the container body. In the present instance the neck has formed thereon a flange 14 which forms a smooth even top surface. A closure member 15 is provided for lcontrolling the outlet' 13. The closure PATENT OFFICE;

member 15 is connected for movement by mean'sin the form of a rivet 16 which extends through an edge portion of the closure member, and an edge portion ofthe flange 14 so as to permit the closure member to be moved to either side `of the neck 12. Means is provided for releasably retaining the closure member in closed position, the saidmeans beingoperable'to retain the closure member in closed position in response to the movement of the closure member in either direction, said closure memberbeing also releasable from the influence of the means which .retains it in a closed position, upon movement of the closure member in either direction.` The retaining means, in

the present instance includes a convexed.

prominence or sector 17. on the under side of the flange 14 at a point diametricall opposite the point of connection of the'c osure member 15 with the flange 14. The retaining means also includes a spring 18 on the closure member 15 at a point diametrically opposite to the pointof pivotal connection of the closure member. The spring 18 'is formed with` a portion 19 which extends laterally and in the plane of the closure member 15, 'a portion 20 which extends substantially at a. right' angle with respect to Athe portion 19, and a portion 21 w ich is substantially parallel to the portion 19. The portion 21 terminates in a concaved extremity or sector 22 having a cam-like terminal 23 at either side of the concavity.f It will be apparent that the formation of the spring is such that a handle is in fact provided. It

will be obvious that when the spring 18 is` mani ulated to'impart pivotal movement to the c osure member 15 from the position kshown 1n Fig. 1, that coaction will be set up between the concaved extremity 22 and the prominence 17 on the under side of the Bange 14, and 'as a conse uence the closure Imember 15. willbe releasa ly retainedA in a closed position as shown most clearl Fig. 3. The coaction of the concave tremity 22 and the prominence 17 results byvirtue of the flexlng of the spring 18, brou ht about by one of the cam-like termina s riding over the convex, surface of the prominence. 17 until the prominence is disposed in the concavity. This action'. takes place regardless of the direction in which the closure member is moved. Furthermore the closure member may be just as conveniently and easily moved to an open position regardless of the direction in which the closure member is moved.

When the closure construction of the present invention is applied toa comparatively large container, the flange on the neck may be omitted, and the closure member will be connected directly to the `neck and so will the convex prominence 17, and the spring 18 may be obviously modified so that the concaved extremity and its cam-like terminals may coact with the prominence.

I claim:

1. A discharge end construction for a container comprisingr a neck having an outlet, a closure member for controlling the outlet, said closure member pivotally connected for movement to either side of the neck` a laterally disposed combination spring and handle on the closure member for effecting the movement thereof, said combined spring and handle embodying a concavity and convexities at opposite sides of the concavity respectively, a convex prominence on said neck, said convex prominence adapted to enter said concavity and to be `removed theremovement of the closure member in either Y direction.

2. A discharge end construction fora container comprising a neck havin." a fiange and an outlet, a closure member for controlling the outlet, said closure member connected for movement by a means which permits the closure member to be moved to either side of the neck, a spring on the closure member formed with a central concaved portion with a cam-like portion at either side of the concayed portion, a' conveXed prominence on Vthe under side of said flange, each cam-like portion riding on the convexed prominence to flex the spring in the movement of the closure member to a closed position to bring the concaved portion in place to receive the convexed prominence. 4
